i feel really stupid right now :S:S:S
anyway, the only advice i can give u is how many/which tricks per table. i can't help u with prices coz i'm not from the us...
anyway, for each table u want to perform about 3 tricks, u would usally want the first one to be visual, anything u can think of actually... it can be coins, sponge balls, even cards (joker's wild is good).
also, u want want the 3 tricks to have: 1 with cards, 1 with coins, and 1 something else.
u also want a connection between the effects, if u have a patter for all 3, that would be the best.
u can also come up with diffrent routines for diffrent people. for kids u would probably want to have the most visual effects that u can, so a good routine for that could be:
silk vanish and reappear
coins across (in the hands)
that's ovcorse just an advice... u can patter as much as u like with it.
ovcorse that u can have more then 3 tricks per routine, but from what i heard around these forums, 2-3 effects is the best.
for older people, u could have longer tricks, that the effect itself happens later. for kids u don't have to really patter, maybe don't even patter at all. but if u want adults to think that ur'e the real thing, u must patter a little bit, like say: "this is kinda hard to do, i need to make all my powers to focus on this..."
or whatever... just make it seem realiable. well, i don't want to undermaste u, so i think u already know what i mean about approaching people to right way, and having people amazed from ur tricks.
if u want to earn tips, the final trick of ur routine can be done with borrowed coins/bills, so they will get the idea of money in ur hands (a bit psychology can't heart
u can also say befor the trick that this would be that last trick u would be performing for them, so they will get the idea ur'e going to leave.
hope this helps a bit,
